IMPROVEMENT IN ENDLESS BELTS.

Specification forming part of Letters Patent No. 82,640, dated September29, 18GB.

To all whom it 'may concern:

Be it known that we, HENRY RICHARDS and JUsTUs A. TEAUT, both of NewBritain, county of Hartt'ord,and State ofConneeticut, have inventedcertain new and useful Improvements in Belts for Polishing, Ste.; and toenable others skilled to make and use the same, we will proceed t0describe by referring to the drawings, in which the same lettersindicate like parts in each of the figures.

The nature of this improvement consists in arranging the threads in anendless position and in Iilling in the roof,.so as to produce an endlesspiece of fabric or belt.

In making belts for (polishing belts) polishing or tinishing regular krirregular forms or surlaces, great ditieuljyis experienced in making thejoint, so asto be even, pliable, and not liable to jump, as it\`(thejoint) passes successively under the work; and also so as not to beliable to come apart, as is Irequently the case as they are now made(with lap-joint) when soaking for relocating, which, or either of'which,`is very annoying, especially where a great number ot' beltsareconstantly being used and recoated.

In the accompanying drawings, Figure 1 represents an endless belt madewhole in one piece ot' fabric. Fig..2 represents one of the heddles,such as we propose to employ in the manufacture of our endless fabricbelts. It is made of metal, and is provided with an open eye to receiveand guide the warp-thread, which is one continuous piece.

To effect this object we arrange a single warpthread upon or overrollers, one of which is arranged near the front part of a loom and theother in the rear part ot' said loom at such distance that the warparrange-d ou said rollers will be about the length required for a belt.This warp-thread is lirst passed around these two rollers and the firstend tied or made fast to the main thread;v then these rollers being setin motion the warp-threadis thus laid from one to the other roller asmany times as may be necessary for the number of threads required forthe warp, and the last end secured to the adjoining thread directlyopposite, or nearlyT so, to therst end.

The harness is or should be so constructed that the warp can be readilyinserted into the eye of the heddles and easily removed therefrom, inorder that after the belt shall have been nearly all woven, which isdone in the ordinary manner of Weaving, the then imperfect action of theheddles due to the limited portion ot' the warp remaining to be wovenmay be avoided, and the last'of the filling-v thread is then to beworked in ny hand'.

We believe we have thus shown the nature,-
